Parenting Coordination is a “hybrid legal‐mental health role that combines assessment, education, case management, conflict management, dispute resolution and, often times, decision‐making functions (AFCC, 2019, https://www.afccnet.org/Portals/0/PublicDocuments/Guidelines%20for%20PC%20with%20Appendex.pdf?ver=2020-01-30-190220-990 ). This article addresses issues that arise when the case has allegations or findings of intimate partner violence (IPV). Considerations of the type of IPV, the severity, timing, perpetrator and effects on coparenting are discussed in the context of the parenting coordinator's role. Through screening and assessment, we differentiate the kinds of cases with the presence of IPV where a PC may be effective as opposed to other IPV cases that may not predict success for retaining a PC. 相似文献

Research examining factors that predict youth’s involvement in organized activities is very limited, despite associations with positive outcomes. Using data from 1043 youth (49% female; 46.4% Hispanic, 35.4% African American, 14.0% Caucasian, and 4.2% other) from the Project on Human Development in Chicago Neighborhoods, this study examined how characteristics of parents (supervision, warmth) and neighborhoods (perceived neighborhood safety and collective efficacy) predict patterns of adolescents’ involvement in organized activities concurrently (i.e., intensity) and longitudinally (i.e., type and breadth). Parental supervision predicted adolescents’ participation in organized activities across multiple waves. Neighborhood violence was positively associated with concurrent participation in organized activities after controlling for socioeconomic status (SES), whereas higher neighborhood collective efficacy predicted greater breadth in organized activity participation across time. These findings have important implications regarding how to attract and sustain organized activity participation for low-income, urban youth. 相似文献

Time spent on social media and making online comparisons with others may influence users’ mental health. This study examined links between parental control over the time their child spends on social media, preadolescents’ time spent browsing social media, preadolescents’ appearance comparisons on social media, and preadolescents’ appearance satisfaction, depressive symptoms, and life satisfaction. Preadolescent social media users (N?=?284, 49.1% female; aged 10–12) and one of their parents completed online surveys. Preadolescents, whose parents reported greater control over their child’s time on social media, reported better mental health. This relationship was mediated by preadolescents spending less time browsing and making fewer appearance comparisons on social media. Parental control over time spent on social media may be associated with benefits for mental health among preadolescents. 相似文献

This paper describes a simplified approach to calculating the Bayesian likelihood ratio for the case where two DNA single locus profiles are to be compared. It explains how the calculation allows for band shift and also for the variation in precision with molecular weight. A simple basic theory section explains the principles of the analysis but more detailed explanations are given in an advanced theory section. Experiments on substantial data collections are described which demonstrate the robustness of the method. 相似文献

A woman pleaded guilty to road traffic offences and was sentenced to be disqualified for holding or obtaining a driving licence for six months. Her appeal against that sentence was allowed on the basis that she was suffering from premenstrual tension at the time of the offences, and that the disqualification imposed was neither necessary nor appropriate. 相似文献
